age of Coal, Ores, &c.,

riores, etc., ,in very large quantities, reaching` `at points remotel siderable distance from the tram-car steam shovels, scoops or suitable height, usually Be it known that I, WILLIAM F. HUNT, a citizenof theUnited States, residing at New Brighton, .Richmond county, State of `New York, have invented certain new. and usefulImprovements in the Storof which the followingis a specification, reference being had to the accompanying drawings, whichform a part hereof. y

It is now a common practice to store coal,

many thousands of tons, from the mines but convenient for distribution. According to the-simplest and most economical methods of handling the coal or other material, as practised hitherto, the

material is brought to the place of storage 1n railway cars, 1s taken out of the cars by above a movable bridge, dumped from the shovel, scoop or bucket into a tram-car whichtravels on the bridge and is run out to the point at which the contents are to be discharged, and is then dumped from the tram-car. no less than three distinct 4handlings 'or breakages of bulk of the material, each `of which ofnecessity adds to the cost of storage. Furthermore, in the case of coal, very serious loss in valve is occasioned by the breaking of the pieces of coal not only at each of the several handlings, but especially in the dumping of the coal from the tramcar. When the pile of coal below the bridge is low, the coal falls through a very conuntil it strikes the bottom of the storage yard or the coal thereon, and therefore acquires considerable velocity and 4has a considerable impact. When the pile -of ycoal is hith, the coal which is dumped on top of e pile does not fall so far, but more or less of it rolls down the inclined side-of the dump and while the velocity of any piece is not very reat,each piece makes many impacts beore it comes to rest. It has been found that the breakage of coal in this manner is in more or less direct proportion to the velocity of its fall and to the number of impacts, and it is well known that the shrinkage in value from this cause is serious.

One object of the invention, therefore, is to effect a reduction in cost of storin coal, ores, etc., byreducing the number o han- Staten Island,

buckets, raised to a There are thus `dlings or breakages'of bulk to a minimum, and also to reduce as much as possible the shrinkage in value of coal due toreduction 1n size through breakage.

' In accordance with the invention the r'ail-` 6or way car in which the coal orvother` material.;l i is delivered at the storage yard, is itself run 'g upon a suitable cage or platform to which itl islsecured', and the cage (as it is commonly called and will be called hereinafter) 14s) 65,. hoisted with the car and its contents and transported bodily to the point of dischar e, where it is lowered to a point 'ust above t top of the pile or dump, and t e contents of the cai` are then discharged, preferably by overturning the cage and car sufficient y to permit the discharge of the coal or other material. There is therefore only one handling or breakage of bulk of the coal or other material between the railway car and 75 the storage pile, with a consequent reduction of cost of storae and a eat reduction of loss through re uction o size of coal, by reason of the elimination of further handlings, together with a still further reduction of such loss -by reason of the reduction of theheight through which the coal fallsl or rolls. It will be understood, of course, that in the storage of large quantities the coal or other material is rst dumped ina comparatively thin stratum over alarge area and that successive strata, also of large area are formed so that there is no opportunit for the coal to roll down the sides of a 'hig y 'd1 11mp, except at the margins of the storage. 90

The invention will be more fully explained hereinafter with reference to the accompanying drawing in which is illus-A trated a convenient form of apparatus with which the invention may be dpractised and in which it is in part embodie In the drawing Figure 1 is a view partly in side elevation butI more or less diagrammatic,illustrating avr desirable form of apparatus for the practice of the invention. Fig. 2 is a view of the same in end elevation. The railway car a in which the coal or other material to be stored is brought from the mine or other point is run directly upon a cage b of suitable construction, to which the car is secured by lookin devices of an suitable character, indicate generally at b The cage b is suspended, as chains c c' from a movable crane d whic is provide cli ned sections g2 with suitable hoisting devices, indicated at e, and is mounted which is itself movable over` the Astorage movably on a bridge f,

`coal or other material is brought from the i mine or; other point,` is run directly upon the `cage and is securedthereto.

carica-d i-s vto be discharged.

By the hoisting devices e the cage, ywith the car and its contents, is then raised toa suitable height so that the cageshall clear the top ofthe ma terial already deposited in the storage yard, and is transported to the pointat which the lVhen that poi-nt is reached the cage is lowered as close as practicable to the surface of the material already placed Ain the yard and the car is then dumped, preferably by taking up the hoisting ropes or chains c, on .one side of tl.=

cage, and lowering away the hoi-sting rc es or'chains c, on the other side of the cage. The -material is thus discharged from the car Without any other handling or breaking of bulk and with the minimum of impact of they pieces, so that breakage of the pieces isalso reduced to a minimum.

The drawing shows atraveling crane or trolley with hoisting engines mounted thereon, but itvwill be understood that,y the hoisting mechanism may-be arranged as may be most convenient.

The coalor ore may be reclaimed for reshipment byv any suitable apparatus.

It willbe obvious that the form of the `apparatus employed may be varied to suit different conditions of' use and that the invention, therefore, is not limited to the particular apparatus shown .and -described herem.

I claim asmy invention l. Apparatus for storing coal, etc., from railway cars comprising a bridge, atrolley mounted thereon, a cage suspended'from the trolley and adapted to receive a railway car,

means to hoist the cage and means to impart a rotary movement to the cagerand car whereby the contents of'the latter are discharged.

2. Apparatus or storing icoal, etc., from railway cars comprisingabridge, a trolley mounted thereon, a cage suspended from the trolley and adapted to receive a. railway car,

means to hoist the cage and means to impart a rotary movement to the cage and car abouttheir longitudinal axis whereby the contents of the car are discharged.' c

3. Apparatus for handling coal, etc., from railway cars comprising a cage, a trolley vmounted 'on a bridge and having twlo sets of hoisting mechanisms, a cage adapted yto receive a railway car, and hoisting ropes connested to the cage on opposite sides and to the several hoistingmechanisms, whereby the car with its contents may be hoisted, transported to thepoint ofdischarge, and

discharged of its contents.

, 4. Apparatus for storing coal, etc., from railway cars comprising a bridge, a"trolley mounted thereon, a' cage suspendedfrom the vtrolley and adapted lto receive a railway car,

mechanism carried on said trolley to hoist the cage and to impart ,arotary' movementto the cage and car whereby the come its of the latter are discharged.
